2.3 Data Processing
The next screen will ask you about data processing. There are 3 options for data processing. This
option is an option to use the internal memory. Up to 1500 "snap-shot" measurements can be stored in
the internal memory. The measurements can be transferred via RS 232 (use data cable item number
1040019) to a PC. Free rbr-software (available on website “ww.rbr.de“) enables the filing of the
recorded data. Please see the Technical Data chapter for data format information. This particular data
processing option is not typically used in North American applications, due to availability of the SDMM
Card and / or Advanced DAS software. If you are using the SDMM Card option and / or the ECOM
Advanced DAS software option, please select
NO
by
pressing the F4 button.
If you do wish to use this option for data storage, you will need additional cables and software to program
the analyzer and to retrieve the data. Please contact ECOM for details.
2.4 Auto Zero / Auto Span
Once all connections are made and the analyzer is switched on, the instrument begins its
automatic Zero / Span procedure. The analyzer should be in fresh air during this period.
During this process, the Oxygen sensor is automatically calibrated to ambient air, (20.9%)
while the other sensors are zeroed and checked for proper signal outputs. The ECOM J2KN
will count down from 60 seconds to complete the Auto Zero/Auto Span warm up period. For
best results, allow the analyzer to acclimate to the ambient temperature, then repeat the Zero
/ Span procedure.
2.5 Normal Measurement Mode
After the instrument has completed its Zero / Span procedure the display will read real-time emission
values. A full screen, with all measured and calculated parameters can be viewed, or the display may
be zoomed to show only 4 parameters. Press the up/down arrow on the keypad to toggle. The
individual parameters can be set on the display by pressing F4, then using the up/down & left/right
keys to select and set the desired view.
Please note: CO2, Efficiency, Lambda, and Losses are calculated values. In order for the analyzer to
begin calculating these values, the Oxygen content has to drop below 20.5% and the T-Gas must be
at least 5 degrees higher than T-Air. When these values are not being calculated, the display will
show "“------"“in these fields.
